Product Features

The complete set of equipment is complete and the voltage level is complete.

Usually, three series of main circuit designs are used: G-type, E-type, and H-type.

Adopting a low-speed gear rack transmission mechanism to adjust the ball clearance at all levels not only reduces noise and wear, but also enables fast and accurate positioning.

The fixed mechanism of the adjustable resistor with spring compression and convenient insertion makes the adjustment convenient and easy to operate.

Adopting an automatic triggering device, the ball gap has a triggering range of over 20%, ensuring good synchronization performance and reliable action.

Adopting constant current charging method, the charging voltage is stable and the instability is not greater than ± 1%.

The resistor adopts a non-inductive winding method to ensure that the overall circuit inductance is small.

When adopting bandstop filtering measures, standard shock waves are still generated under high capacity loads, resulting in high load capacity.

The voltage utilization coefficient is high, with lightning waves not less than 85% and operating waves not less than 70%.

Use an automatic steel strip device to short-circuit and ground the main capacitor.

Adopting computer control system technology, it has a high degree of automation and strong anti-interference ability.

The use of a digital measurement and analysis system for shock waveforms and a computer online processing system for shock test data has high measurement accuracy.

This set of products can generate the following standard waveforms: standard lightning impulse voltage full wave 1.2 ± 30% us/50 ± 20% us; Standard operating shock Voltage wave 250 ± 20% us/2500 ± 60% us; Lightning cutoff time 2-6us; Standard steep wave steepness above 1000kV/us.
